Subject: HOT lanes news
Pricers--
A new PhD dissertation at UCLA school of urban planning reaches very
positive conclusions about HOT lanes--especially in contrast to HOV lanes.
Excerpts from the abstract:
"The results indicate that HOTLs, congestion toll lanes, and GPLs provide a
greater degree of system-wide delay-reduction benefits than HOVLs in most
cases. Furthermore, when maximum mainline peak highway delays are between
20 and 40 minutes, congestion toll lanes provide a greater reduction in
overall delays and emissions than GPLs.
"This research provides support for the policy claim that in almost all
local urban travel conditions, HOT lanes provide a greater degree of
fiscal, consumer welfare, and environmental benefits than all other
line-haul urban expressway investments. HOT lanes are the only urban
highway facilities capable of withstanding induced growth effects, and
preserving congestion-free service after an initial reduction in travel
costs.
"Because HOT lanes preserve congestion-free service in the face of traffic
growth, HOT lanes are more environmentally beneficial than either HOVLs or
GPLs."
You can find this material on Digital Dissertations
(wwwlib.umi.com/dissertations). On that site, you can select "Full Citation
and Abstract", which is a printable page, or "24 Page Preview" which is
also printable. And if you want the entire dissertation, you can order and
pay for it on-line.
I have not read the dissertation yet, and cannot comment on its
methodology, but the fact that it was approved by a dissertation committee
of distinguished scholars (chaired by Brian Taylor) suggests that it will
stand up to critical scrutiny.
